Deputy Chief Rodney Johnson says the five are from Detroit and were arrested Tuesday on outstanding warrants.

Johnson says “it is believed they have a possible connection to the death threat.”

Craig said Sunday that the threat against him was on a social media site and followed the city’s crackdown on drug trafficking. The threat was uncovered Friday. Craig said the threat included a photo of a handgun and the phrase: “We need to clap him out.”

Since July, Detroit police and other agencies have conducted five large-scale drugs sweeps and raids on about 35 drug houses each week.
